Agree with AussieGirl, the health benefits are greater with green - human blood and chlorophyll are remarkably similar. Its hard to make a big jump from sweeter juices that we're used to though so start small if you have to. I enjoyed carrot, celery, beetroot and apple. Something like 2 sticks of celery, half a beet, 1-2 carrots and 1/2-1 apple (all depends on size). There is a great book which is really cheap by the woman who is known as 'The Juice Lady' - Need to double check name spelling (on my iphone) but its by Sherie Cabom or something like that. Loads of recipe suggestions and for different ailments, like if youre trying to ward off a cold or infection etc.
